This lunchtime (1-2pm) we're very lucky to be able to welcome Olympic swimming champion Rebecca Adlington onto the forums. She'll be answering your questions about achieving your potential in the pool, her own experience of swimming at the highest level and of course, her journey to next year's London Olympics.
Rebecca is currently riding high as Britain's most famous swimmer. Her success over 400m and 800m at the Beijing Olympics - including smashing Janet Evans's long-standing 800m world record - has made her the most successful female swimmer we've had for decades.
We're opening the discussion now Rebecca so can get answering your questions straight away at 1pm (rather than having to deal with a rush of questions at once).
[Edited - Sean Kelly's not actually here again, that bit of text got dragged through from last week...]
